The Administrative Core is organized to provide support and oversight for the Program Projects. It is designed to facilitate exchange of ideas and scientific interactions among Projects and Cores. Core A will continue to serve as the communication center where our internal and external committees can channel their comments to individual project/core leaders, as well a central place that the Internal and External Advisory Boards can monitor project progression. Core A will keep our internal advisory board (Drs. Bennett, Haskins, June and Wright) and our external advisory board (Drs. Bray, Hedner and Schaub) updated about experimental outcomes on a semi-annual basis. It will provide services to individual projects in areas such as budget control, abstract and manuscript preparation, and meeting scheduling.
